chore(rebar): Pier_T_rebar 작업 폴더 초기 구성 및 외부 의존 파일 통합

- Code\rebar_pipeline, review_pipeline, pier-program을 정션에서 실제 폴더로 전환
- Code\rhino_mcp 및 CLAUDE_rhino배경.md 추가, .mcp.json은 PYTHONPATH로 새 위치 사용
- pier-program 내부 .git 제거(이력은 backup\pier-program_20261028.bundle에 보관)
- worktree 가이드 반영(CLAUDE.local.md, HANDOFF.md)
- D:\Rhino-MCP 경로 참조를 새 위치로 치환

+# Coding Conventions
+
+> Phase 2 Deliverable: Code writing rules definition
+
+**Project**: {{project_name}}
+**Date**: {{date}}
+**Version**: 1.0

+
+## 1. Naming Conventions
+
+### 1.1 Files/Folders
+| Target | Rule | Example |
+|--------|------|---------|
+| Component files | PascalCase | `UserProfile.tsx` |
+| Utility files | camelCase | `formatDate.ts` |
+| Folders | kebab-case | `user-profile/` |
+| Constant files | UPPER_SNAKE_CASE | `API_ENDPOINTS.ts` |
+
+### 1.2 Code
+| Target | Rule | Example |
+|--------|------|---------|
+| Components | PascalCase | `UserProfile` |
+| Functions | camelCase | `getUserById` |
+| Variables | camelCase | `userName` |
+| Constants | UPPER_SNAKE_CASE | `MAX_RETRY_COUNT` |
+| Types/Interfaces | PascalCase | `UserProfile` |
+| Enum | PascalCase | `UserRole` |
+
+---
+
+## 2. Folder Structure
+
+```
+src/
+├── components/         # Reusable components
+│   ├── ui/            # Basic UI components
+│   └── common/        # Common components
+├── features/          # Feature-based modules
+│   └── {{feature}}/
+│       ├── components/
+│       ├── hooks/
+│       └── types.ts
+├── hooks/             # Common custom hooks
+├── utils/             # Utility functions
+├── types/             # Global type definitions
+├── constants/         # Constants
+└── styles/            # Global styles
+```
+
+---
+
+## 3. Code Style
+
+### 3.1 General
+- Indentation: 2 spaces
+- Quotes: Single quotes (')
+- Semicolons: None
+
+### 3.2 Functions
+```typescript
+// Preferred: Arrow functions
+const handleClick = () => {
+  // ...
+}
+
+// Components: function declaration
+function UserProfile({ user }: Props) {
+  return <div>{user.name}</div>
+}
+```
+
+### 3.3 Import Order
+```typescript
+// 1. External libraries
+import { useState } from 'react'
+
+// 2. Internal modules (absolute paths)
+import { Button } from '@/components/ui'
+
+// 3. Relative paths
+import { useUser } from './hooks'
+
+// 4. Types
+import type { User } from '@/types'
+
+// 5. Styles
+import './styles.css'
+```
+
+---
+
+## 4. Component Rules
+
+### 4.1 Structure
+```typescript
+// 1. Import
+// 2. Type definition
+// 3. Constants
+// 4. Component
+// 5. Export
+```
+
+### 4.2 Props
+```typescript
+interface Props {
+  user: User
+  onSelect?: (user: User) => void
+}
+```
+
+---
+
+## 5. Environment Variable Conventions
+
+### 5.1 Naming Rules
+| Prefix | Purpose | Exposure |
+|--------|---------|----------|
+| `NEXT_PUBLIC_` | Client-side accessible | Browser |
+| `DB_` | Database | Server only |
+| `API_` | External API keys | Server only |
+| `AUTH_` | Authentication | Server only |
+
+### 5.2 .env File Structure
+```
+project-root/
+├── .env.example        # Template (included in Git)
+├── .env.local          # Local development (Git ignored)
+├── .env.development    # Development environment
+├── .env.staging        # Staging environment
+└── .env.production     # Production (no sensitive info)
+```
+
+### 5.3 Environment Variable List
+| Variable | Purpose | Exposed | Secrets |
+|----------|---------|:-------:|:-------:|
+| `NEXT_PUBLIC_APP_URL` | App URL | ✅ | |
+| `DATABASE_URL` | DB connection | | ✅ |
+| `AUTH_SECRET` | Auth secret | | ✅ |
+| | | | |
+

+
+## 6. Clean Architecture
+
+### 6.1 Layer Structure (Level: {{level}})
+
+**Starter**:
+```
+src/
+├── components/     # UI
+├── lib/            # Utilities
+└── types/          # Types
+```
+
+**Dynamic**:
+```
+src/
+├── components/     # Presentation
+├── features/       # Application + Presentation
+├── services/       # Application
+├── types/          # Domain
+└── lib/api/        # Infrastructure
+```
+
+**Enterprise**:
+```
+src/
+├── presentation/   # UI, hooks
+├── application/    # services, use-cases
+├── domain/         # entities, types
+└── infrastructure/ # api, db
+```
+
+### 6.2 Dependency Rules
+| Layer | Can Depend On | Cannot Depend On |
+|-------|---------------|------------------|
+| Presentation | Application, Domain | Infrastructure directly |
+| Application | Domain, Infrastructure | Presentation |
+| Domain | None (independent) | All external layers |
+| Infrastructure | Domain | Presentation |
+
